I have been pulling my hair out on a RedHat 64 bit install. Yes installed MySQl and all the 32 bit drivers, tried commercial and the GA versions but nothing works for CRS2008. 32 bit unixODBC and isql etc are all fine though so it is not a connectivity issue.
I have also duplicated the install to RedHat 32 bit but it doesn’t seem to make any difference.
Also to confirm it isn’t the reports (were also created with a client with the same version number), I have the same reports deployed to a Windows 2008 R2 server running the same BOXI version and the reports run fine both to local and remote MySQL databases using ODBC… Again 64 bit host OS but 32 bit ODBC drivers.
Note that there must be NO WHITE SPACE between any DSN variable name = and the value and no # comments either!
The SAP ODBC install configuration document even has an example that does have them and it did not work.
The unixODBC standard for the /etc/odbcinst.ini having the driver details in and the odbc.ini referencing the ODBC driver alias also doesn’t work you have to specify the actual driver file in the link file or the odbcinst.ini alias.
